DETAILED DESCRIPTION

Examples will be described in detail herein with the examples thereof expressed in the drawings. When the following descriptions involve the drawings, like numerals in different drawings represent like or similar elements unless stated otherwise. The implementations described in the following examples do not represent all implementations consistent with the present disclosure. On the contrary, they are merely examples of an apparatus and a method consistent with some aspects of the present disclosure described in detail in the appended claims.

A three-dimension (3D) holographic content is a new content collection and presentation technology which can more realistically reproduce a real 3D geometry and light information of a collected object than an ordinary two-dimension (2D) content. This technology is especially applicable to collecting a dynamic real person. In recent years, with development of holographic collection hardware, and reconstruction or compression software, fabrication and propagation of holographic contents become more convenient. However, often the holographic content cannot be correspondingly adjusted in pose based on a change of a relative position of a photographing device.

FIG. 1 is a flowchart illustrating a method of adjusting a holographic content according to an example of the present disclosure. As shown in FIG. 1, the method of adjusting a holographic content may be applied to an electronic device. The electronic device may include but not limited to an intelligent device such as intelligent glasses and an AR mobile phone. The method of adjusting a holographic content includes the following blocks S101-S103.

At block S101, a pose of an electronic device and a pose of a holographic content are obtained respectively under a current spatial coordinate system.

The pose can include, for example, position and attitude. The position can include, for example, coordinates in a three-dimensional (3D) space measured by sensors such as optical sensors (e.g., cameras), positioning systems such as the global positioning system (GPS), wireless network such as Wi-Fi or cellular network, etc. The attitude can include, for example, yaw, roll, and pitch measured by an attitude sensor such as a gyroscopic sensor, a micro-electromechanical (MEMS) sensor, an accelerometer, etc.

The current spatial coordinate system may be a camera spatial coordinate system of the electronic device.

In some embodiments, before performing block S101, the method further includes: detecting whether a second visual sensor in the electronic device is enabled; if yes, obtaining the pose of the electronic device and the pose of the holographic content respectively under the current spatial coordinate system. For example, by taking an AR device as an example, it is detected that whether a camera in the AR device is enabled. After it is detected that the camera in the AR device is enabled, the pose of the AR device and the pose of the holographic content are obtained respectively under the current spatial coordinate system.

The origin of the current spatial coordinate system is a position where the electronic device, for example, the AR device, is enabled.

In some examples, the pose of the electronic device, for example, the AR device, i.e. (x_(camera), y_(camera), z_(camera), yaw_(camera), roll_(camera), pitch_(camera)) and the pose of the holographic content, i.e. (x_(holo), y_(holo), z_(holo), yaw_(holo), roll_(holo), pitch_(holo)) may be obtained in real time at six dimensions of the current spatial coordinate system.

As above, yaw refers to a yaw angle, roll refers to a roll angle, and pitch refers to a pitch angle.

At block S102, difference information between the pose of the electronic device and the pose of the holographic content is obtained.

The difference information between the pose of the electronic device and the pose of the holographic content may be obtained by obtaining differences of poses at six dimensions.

At block S103, the pose of the holographic content is adjusted if it is determined that the pose of the holographic content is to be adjusted based on the difference information.

In some examples, if it is determined that a display region of the holographic content exceeds a preset range based on the difference information, it is determined the pose of the holographic content is to be adjusted. For example, if a holographic person is locally or wholly outside a photo preview window, it is determined that the pose of the holographic content is to be adjusted.

The fact that the display region of the holographic content exceeds the preset range may be determined in many manners. For example, if the difference information indicates that an absolute value of a difference at any dimension of the current spatial coordinate system is greater than a preset threshold, it is determined that the display region of the holographic content exceeds the preset range. For another example, if the difference information indicates that an average difference at a plurality of dimensions of the current spatial coordinate system is greater than a preset value, it is determined that the display region of the holographic content exceeds the preset range.

The pose of the holographic content may be adjusted in several manners, for example, in the following manners.

In a first manner, the holographic content is rotated or moved based on the difference information under the current spatial coordinate system.

In a second manner, kinematic information of the electronic device under the current spatial coordinate system is determined and a holographic content matched with the kinematic information is obtained as an adjusted holographic content.

For example, if the AR device is rotated rightward by 5 degrees under the current spatial coordinate system, a holographic content video clip matched with the current kinematic information is obtained as the adjusted holographic content.

In a third manner, new feature information of the holographic content is dynamically synthesized based on skeleton information of the holographic content with a computer vision algorithm and taken as the adjusted holographic content.

The new feature information may include but not limited to new geometric features and texture features and so on.

In the above examples, the pose of the electronic device and the pose of the holographic content are obtained respectively under the current spatial coordinate system, and the difference information between the pose of the electronic device and the pose of the holographic content is obtained, and then the pose of the holographic content is adjusted. In this way, the pose of the holographic content may be adjusted correspondingly according to a change of a relative position of the electronic device.

FIG. 2 is a flowchart illustrating a method of adjusting a holographic content according to another example of the present disclosure. As shown in FIG. 2, after block S103, the method further includes the following block.

At block S104, the holographic content is rendered based on an adjusted pose.

In some examples, after the pose of the holographic content is adjusted based on the difference information, a corresponding holographic content may be rendered based on the adjusted pose to produce a real-time preview effect.

In some examples, the electronic device may obtain a rendered holographic content by rendering the holographic content based on the adjusted pose.

FIG. 3 is a flowchart illustrating a method of adjusting a holographic content according to another example of the present disclosure. As shown in FIG. 3, after block S104, the method further includes the following block.

At block S105, if a collection instruction is obtained, synthesis is performed for the current holographic content and an image collected currently by a first visual sensor in the electronic device to generate an image.

If the first visual sensor, for example, a first camera, in the electronic device, obtains the collection instruction, image collection is started, and the current holographic content and the currently-collected image are synthesized to generate an image. In this way, a group photo may be taken for a user and a generated image.

In some examples, the current holographic content may be the rendered holographic content. At this time, if the collection instruction is obtained, synthesis is performed for the rendered holographic content and the image collected currently by the first visual sensor in the electronic device to generate an image. In this way, a group photo may be taken for the user and a generated image.

At block S106, if a photographing instruction is obtained, the image is stored.

In some examples, if a photographing instruction is obtained by a second visual sensor, for example, a second camera, in the electronic device, the generated image is stored.

In the above examples, synthesis is performed for the current holographic content and the image collected currently by the first visual sensor in the electronic device to generate an image. When the photographing instruction is obtained, the image is stored. Thus, interactive experiences between the user and the holographic content are increased.

Some embodiments of the present disclosure will be illustratively described below in combination with FIG. 4. As shown in FIG. 4, a visitor A wearing first AR glasses 41 visits a company and desires to take a group photo together with holographic persons at the door of the laboratory of the company. The visitor A stares in a direction of a camera 421 in second AR glasses 42. Under the current spatial coordinate system, the second AR glasses 42 may obtain the pose of the second AR glasses and the pose of the holographic person and may adjust the pose of the holographic person based on difference information therebetween, that is, the holographic person may adjust its own position and orientation based on a position and an orientation of the camera 421 to achieve an ideal group-photographing effect.

Similarly, as shown in FIG. 5, the second AR glasses 42 may be replaced with an AR mobile phone 43. That is, the group photo is taken by the AR mobile phone 43. At this time, if a camera of the AR mobile phone 43 rotates horizontally by 10 degrees, the holographic person will rotate by 10 degrees correspondingly, thereby achieving a good interaction with the visitor.

FIG. 6 is a flowchart illustrating a method of adjusting a holographic content according to another example of the present disclosure. As shown in FIG. 6, after block S104, the method further includes the following block.

At block S107, if a photographing instruction is obtained, an image is generated based on the current holographic content and then stored.

If the photographing instruction is obtained by the second visual sensor, for example, the second camera, in the electronic device, the image may be generated based on the current holographic content and then stored.

In some examples, the current holographic content may be the rendered holographic content. At this time, if the photographing instruction is obtained, the image is generated based on the rendered holographic content and then stored. Thus, a virtual object can be photographed.

In the above examples, the virtual object is photographed by generating the image based on the current holographic content and storing the generated image.

Corresponding to the above examples of the method of adjusting a holographic content, the present disclosure further provides an example of an apparatus for adjusting a holographic content.

As above, yaw refers to a yaw angle, roll refers to a roll angle and pitch refers to a pitch angle.

For example, if a holographic person is locally or wholly outside a photo preview window, it is determined that the pose of the holographic content is to be adjusted.

In the above examples, the pose of the electronic device and the pose of the holographic content are obtained respectively under the current spatial coordinate system, and the difference information between the pose of the electronic device and the pose of the holographic content is obtained, and then the pose of the holographic content is adjusted. In this way, the pose of the holographic content may be adjusted correspondingly according to a change of a relative position of the electronic device.

Implementations of the subject matter described in this disclosure can be implemented as one or more computer programs, i.e., one or more modules of computer program instructions, encoded or stored on one or more non-transitory computer-readable storage medium for execution by, or to control the operation of, data processing apparatus.

Alternatively, or in addition, the program instructions can be encoded on an artificially-generated propagated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus for execution by a data processing apparatus. A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them.

Moreover, while a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially-generated propagated signal. The computer storage medium can also be, or be included in, one or more separate components or media (e.g., multiple CDs, disks, drives, or other storage devices). Accordingly, the computer storage medium may be tangible.

The operations described in this disclosure can be implemented as operations performed by a data processing apparatus on data stored on one or more computer-readable storage devices or received from other sources.

While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any claims, but rather as descriptions of features specific to particular implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombinations.

Moreover, although features can be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination can be directed to a subcombination or variations of a subcombination.

Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing can be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.

As such, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking or parallel processing can be utilized.
